Tidal Islands

Do you know what Tidal islands are? The best definition of a tidal island that I can find says that it is a piece of land that is connected to the mainland by a natural or man-made causeway that is exposed at low tide and submerged at high tide.

This image here shows clearly how a piece of the mainland becomes an island at some times in a day (depending on the tides as said earlier). Such tidal islands exist in many places in the world. In Asia, such islands are present in Hong Kong and South Korea. Europe has the highest number of tidal islands. North America and Oceania also have a good number of them. Let's know about few of the above.

South Korean Islands - Jindo and Modo
"Moses Miracle"is a local phenomenon due to the tide-related sea level variations. A land pass 2.9 km long and 10–40 meters wide opens for an hour between Modo and Jindo islands approximately twice a year, around April-June. It had long been celebrated in a local festival called "Jindo's Sea Way". Nowadays, nearly half a million foreign and local tourists attend the event annually.

Popularly nicknamed "St. Michael in peril of the sea" by medieval pilgrims.
